--- Comment #3 from Todd Richmond <todd_richmond at hotmail dot com> ---
We have been using the same build setup for the last 20 years and this is the
1st gcc failure :) We build EVERYTHING in a self contained fashion and don't
rely on any OS libraries except libc.so.
I don't know what file normally defines PTR, but someone else must have run
into this for the patch to have been checked in
Below log is from a CentOS 7 compile using gcc 12.1
